Maybe less underrated than forgotten. Outland starring Sean Connery💫

Strange Days

Edge of Tomorrow

2010: THE YEAR WE MAKE CONTACT The 1984 sequel to “2001: A Space Odyssey” (1968)… It feels like the film is overlooked quite a bit, but it’s a really good sci-fi movie that continues the ‘2001’ story & is based on an Arthur C. Clarke book. It also had a phenomenal cast including the likes of Helen Mirren, Roy Scheider, Keir Dullea, John Lithgow, and Douglas Rain (again providing the voice of HAL 9000). It’s certainly worth a watch! [No Ai/Bots] [Image: UA/MGM]

'Set in the year 2047, Event Horizon follows a group of astronauts on a rescue mission to investigate a once-missing spaceship that has just returned near Neptune...'

'A conceptual sci-fi that explores the ‘what if’ of the existence of another Earth, through a woman’s attempt to find redemption following a tragic and unforgivable mistake...'

Prometheus

One of Jeff Bridges' best films

Based on a book by Michael Crichton

'Darren Aronofsky puzzled audiences and critics alike with his enigmatic The Fountain. Viewers were divided in their opinions of the film, regarding it as a modern masterpiece or a bombastic work of ego...'

Blade Runner

Not best of all time, but little-known and very much worth watching, preferably with no foreknowledge whatsoever.

Maybe Heavy Metal! I love that movie! I distinctly remember watching it while trying Salvia all by myself, and the green orb was cornering the girl, and she screamed, "Help!" - I was so screwed up from the Salvia I actually thought, "Who, me? Am I supposed to help this chick?" Great movie! LOVE it.

Tron (1982)

Coherence (2013) — one dinner party, infinite timelines.

The Andromeda Strain.

(Maybe under-watched)

'The 1970 film is about an advanced American defense system named Colossus becoming sentient. After being handed full control, Colossus' draconian logic expands on its original nuclear defense directives to assume total control of the world and end all warfare for the good of humankind, despite its creators' orders to stop.'

Reign of Fire!

A 1962 movie about the aftermath of a nuclear war. Very understated but that makes it effective

Sunshine is a great movie from 2006 with Cillian Murphy. A must watch for late-night viewing

underrated sci-fi TV show : FutureMan

Star Trek lll: The Search For Spock..it's got everything - the tension, James Horner's music, sabotage, majesty, the clunky engine sounds when the Excelsior comes to a dead stop and when Scotty quips "The more they overthink the plumbing, the easier it is to stop up the drain"...

city of ember

Most underrated "sci-fi" movie of all time? Dark City (1998) A neo-noir mind-bender about memory, identity, and alien manipulation in a perpetually night-bound world. Underrated for its groundbreaking production design that influenced The Matrix, yet it bombed at release. An awesome watch even in 2025!

A great film with James Caan (who was also in Rollerball)

Sunshine

Primer

Ex machina

THX 1138 (1971) - a truly visionary film from George Lucas

A worthy sequel to 2001:A Space Odyssey

A fun movie from 1980, seen either as a tribute to or a rip-off of Star Wars
